No actually, I learned this from my previous and previous game. Its not gonna mucked up the economy in game. But actually, the economy will be more stable soon after 2 or 3 month. When player know how to control the economy in game.xD But please realize something. In BK, the costume that they selling is MOSTLY permanent one. Still not sure whr they got it. But only a few selling CS's item with duration in game. If CS's if sellable in game, OS also getting more profit from this. More and more ppl will buy SC and spend the CS thing in game rather then use it their self coz its kinda stupid to purchase a lot of CS things and only use it for 1 character and cant share with other character. And can only getting in game money by making enhance service that use up to 25$ dollar for one +9. Dont you think?
